Application filed April 14, 1911. Serial No."621,053.

Pennsylvania, have invented a new and use-' ful -Dumb and Bar Bell and Ring-Weight,

of which the following is a specification.

My invention consists of improvements in an exercising device of the order of a dumb and bar bell and a ring weight, as will be hereinafter set forth, the novel features of the same being pointed out in the claims.

The invention is satisfactorily illustrated in the accompanying drawing, but the important lnstrunientalltles thereof may be varied, and so it is'to be understood that the invention is not limited to the specific arrangement and organizationshown and described.

dumb and bar bell embodying my invention.

sectional shells of the device taken at the diameter thereof. Fig. 3 represents a section of a portion on line mmFig. 1. Fig. 4

applied. Fig. 7 represents a plan view of the shell at a pole thereof. Flg. 8 represents a side elevation of a portion of the device, and section ofa handle thereon adapting the device as a ring weight. Fig. 9 represents a side elevation of one of the weight plates employed. Fig. 10 represents an end view of a portion of one of the sections of the shell taken at the diameter thereof.

responding parts in the figures.

Referring to the drawings z-A designates a spherical shell which is composed ofthe separate hemispherical sections B and forming a hollow body. TllB'SQClJlOIl 13 1S:

Passing through the are depressed as at G, H, the depression G receivingthe collar J, the inner portion of which is provided with a'neck K which with said collar is fitted on the rod E, and secured to the latter by the bolt or rivet L, which is passed through said neck and'collar. The depression H receives the nut M which is screwed upon a threaded portion of the adjacent end of the rod E, thus tightly seating the collar J onthe face ofthe depression G and clamping together the sections B and C as one and firmly connecting said rod with the shell A.

In order to prevent therotation of the collar J on the shell A, the face N ofthe depression G and the circumferentialwall P of'said collar are of elliptical form as shown in Fig. 3, the effect of which is evident.

1 The section c contains the weight plates Q, Figure'l represents a partial diametrlcal section and a partial side elevation of a1 of different diameters, the same being placed one against the other and fitted centrally on the rod E they interlocking with each other by means of the projecting tongues R and grooves S one of each of which is formed on the respective plate, so that the tongue of one plate enters the groove ofthe contiguous plate. The wall D has on its side toward the plate Q, the tongue T which is adapted to enter the groove-S of the adjacent plate.

In the periphery of the wall D are the recesses U andon the inner faceof the section C are the segmental beads V the latter extending from the diameter of the section to the pole ofthe same. In the peripheries of the plates Q are recesses W, it being noticed that said beads V are adapted to --enter-said recesses U of the wallD, and said recesses W of the plates Q. by which means the plates are interlocked with each other and also with the 'wall D and the section C, the sections B C being also interlocked with each other; all in such manner that the plates are prevented-fromrotating in the section C, and the sections B C are prevented from rotating on each other, the plates as is evident being compactly held together comparatively as a solid structure with, the section C and so are without liability to rattle or shift in any direction.

The section B is adapted to contain shot, pellets or pieces of loose material for adjustably loading or weighting the shell as heretofore practiced. Access is had to the in terior of said section through the opening or inlet X which is closed by the cap or stopper Y, the wall of said opening having outturned recesses Z therein and said cap having on its inner side the tongues Y which are adapted to be passed through said recesses into the section while the cap is seated on said inlet X on the exterior of the section. Then when the cap is partly rotated, the tongues turn with the same and leave the recesses Z when they ride on and across the inner side of the wall of said inlet and so look the cap to the shell. Secured to the inner side of said cap is the plate spring Y whose ends are adapted to be interposed between the cap and the face of the opening X and so create friction on the cap and prevent rotation of and release of the latter, but when the cap is properly rotated until the tongues Y register with the recesses Z, the cap is no longer controlled by the wall around the inlet and so may be withdrawn and access provided to the interior of the section B. Secured to the wall D and the pole of the section B at the depression G is the sleeve E, the rod E being adapted to pass through the same whereby should said rod be removed the openings in said wall and pole will be closed from within the section so as to prevent the shot or loose weights in said section from escaping through said opening.

Referring to Fig. 8 when the device is intended as a ring weight, there is connected with the rod E, the handle E shown partly broken off, at the base of which is the collar J shown in dotted lines, the same being similar to the collar shown in Figs. 1 and 3, said collar being seated in the depression G in said figures. The handle portion F of the rod as such is dispensed with, it being evident that the shell with its interior weights may be carried by the handle E and manipulated by the same as a ring weight for exercising purposes.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is 2- 1. In an exercising device, a hollow spherical body, a plurality of weight plates there in, a head on the interior face of said body, grooves in the peripheries of said plates, and tongues and grooves respectively on and in the contiguous faces of said plates being between the peripheries and centers of said plates.

3. In an exercising device, a hollow spherical body, a bead on the interior face thereof,

and a weight plate in said body, the plate having on the circumference thereof a groove adapted to receive said bead for interlocking said plate with said face of the shell.

4. In an exercising device of the character stated, a hollow spherical body formed of separate sections, means for connecting the same, a bead on the inner face of one of said sections, and a groove on the diametrical portion of the other section, said beadbeing adapted to enter said groove for interlockingthe sections and preventing rotation of the latter one on the other.

5. In an exercising device of the character stated, a hollow body, an opening being formed therein, a rotatable cap adapted to close said opening, means for retaining the cap in closed position and a plate spring on the inner side of said cap secured thereto, said spring being adapted to rotate with said cap and its ends engaging the face of said opening.

6. In an exercising device of the character stated, a hollow body having a partition wall, an opening in the outer wall of the body, said opening having out-turned recesses, a cap fitted to said opening, diametrically disposed arms extended beyond the opposite edges of said cap and adapted to enter said recesses, and a spring disposed at an angle to said arms and adapted to he between the cap and the Wall about said Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents, Washington, D. 0.
